Another electrical connector (flat male terminal) is inserted into the tubular portion 20 between the upper inner wall of the tubular portion 20 and the spring contact piece 20a. This causes the spring contact piece 20a to bend downward,
It abuts the reinforcing piece 20d to elastically deform the reinforcing piece 20d. As a result, the other electrical connector is pressed by the spring contact piece 20a and the reinforcing piece 20d with a predetermined pressing force. That is, even when the pressing force of the spring contact piece 20a alone becomes small when the wall thickness of the tubular portion 20 becomes small, the pressing force is complemented by the reinforcing piece 20d and a predetermined pressing force is obtained. As a result of obtaining the predetermined pressing force, it is possible to improve the reliability of mutual electrical connection of the electrical connectors.

According to the electrical connector described, a tubular portion into which the other electrical connector is inserted, and a spring contact piece formed on the inner wall of the tubular portion and elastically contacting the other electrical connector are provided. In the electrical connector, a reinforcing piece is formed below the spring contact piece by cutting and raising the tubular portion so that the spring contact piece abuts and elastically deforms when the other electrical connector bends due to insertion. Therefore, when another electric connector is inserted into the tubular portion to bend the spring contact piece, the spring contact piece abuts the reinforcing piece and elastically deforms the reinforcing piece. Therefore,
Even if the spring constant of the spring contact piece is small, a large contact pressure can be obtained by complementing the reinforcing piece, and the reliability of the electrical connection between the electrical connector of the present invention and another electrical connector is improved. Can be increased.
